Fire Fighting Measures
Flammability:
Not Flammable
Combustibility:
Does not burn or burns with difficulty.
Extinguishing Media:
Extinguish fires using media suitable for underlying cause.
Dry chemical, foam, and CO2 extinguishing media are
suitable.
Hazardous
Combustion Products:
Carbon dioxide, carbon monoxide, sulphur compounds,
nitrogen oxides. Water used in fire-fighting may result in
release of MITC.
Precautions for Fire
Fighters:
Wear full protective clothing and self-contained breathing
apparatus.

Accidental Release Measures
Emergency Procedures:
Clear area or unprotected persons. Wear protective
clothing:

Cotton overalls buttoned to the neck and wrist
(or equivalent clothing) and a washable hat.

Goggles.

Elbow length nitrile or neoprene gloves.

Chemical resistant footwear. Do NOT reuse
footwear until thoroughly aired.

Half-face respirator with organic vapour/gas
cartridge.
Shovel or sweep into a container and seal immediately.
Avoid raising dust. Do NOT flush area of spill with
water. Do NOT flush to drains or sewers. Do NOT
contaminate streams, rivers or watercourses.
Depending on the quantity released to the
environment, notification to regulatory authorities may
be required. If spill is to a water body, immediately
notify applicable authorities downstream, so that
contingencies can be taken.

Handling:
Handling and Storage
Do not eat, drink or smoke while handling the product. Avoid
breathing dusts or vapours. Always use product in well-ventilated
areas. Remove contaminated clothing immediately. Wash after using
product.
Avoid dust formation. Dust can form an explosive mixture with air.
Prevent electrostatic charge – sources of ignition should be kept well
clear and fire extinguishers should be kept handy.
Storage:
8
8

Engineering Controls:
Use local ventilation.
Personal Protective
Equipment:
Clothing:
Cotton overalls buttoned to the neck and wrist.
Eyes:
Goggles.
Hands:
Elbow length nitrile or neoprene gloves.
Feet:
Chemical resistant footwear. Do NOT reuse footwear
until thoroughly aired.

recommended during use.
9 Physical and Chemical Properties
Appearance:
White to yellowish micro-granules with slightly
pungent odour
Melting Point:
104°C
Vapour Pressure:
0.3 x 10-5 mbar
Solubility (water):
3.6 g/kg
Density:
0.8 g/cm3 @ 20°C
Flash Point:
Approx. 93°C
Minimum ignition energy:
>1.3J
Flammability:

10 Stability and Reactivity
Chemical Stability:
Normally stable. Will decompose in the
presence of water to form methyl isothiocyanate
(MITC).
Conditions to Avoid:
Moisture.
Incompatible Materials:
Water
Hazardous Decomposition
Products:
Carbon dioxide, carbon monoxide, sulphur
compounds, nitrogen oxides.
Hazardous Reactions:
Dust explosion hazard. Contact with water or
moisture liberates toxic gases.
11 Toxicological Information
Acute
Swallowed:
Moderately toxic: 360 – 620 mg/kg (rat, rabbit)
In Eyes:
May cause eye irritation.
On Skin:
Low toxicity: LD50 > 2000 mg/kg (rats). Causes skin irritation
and sensitisation.
Inhaled:
8.4 mg/L (rat)
Chronic
No significant toxic effects have been observed in animal
testing or in actual use.
12 Ecological Information
Toxic to algae and fish.
Ecotoxicity:
Rainbow trout 96 hr LC50:
4.5 – 10 mg/L
Daphnia magna 48 hr LC50:
0.4 mg/L
Mallard Duck LC50:
415 mg/L
Bacterial Toxicity 17 hr EC10:
1.8 mg/L
Persistence /Degradability:
Half life in air estimated to be 1.3 hours. In
moist soils and water, readily hydrolyses to yield
methyl isocyanate, hydrogen sulphide and methyl
amine.
Mobility:
Expected to be highly mobile in soil based on
Koc of 90 (although hydrolysis is expected to
minimise extent of leaching).
Environmental Fate:
Hydrolyses to yield methyl isocyanate, hydrogen
sulphide and methyl amine.
Bioaccumulation Potential:
Low (estimated BCF 3)
13 Disposal Considerations
Disposal Methods:
Shake container empty onto treated area. Destroy empty
containers by breaking, crushing or puncturing them.
Dispose of the containers at a local landfill, or bury the
containers at a depth of 500 mm or more at a licensed
landfill. Do NOT burn empty containers.
Dispose of waste product as hazardous material. Use a
licensed disposal contractor. Do not discharge into
waterways or sewer systems without proper authority.
